What We Offer

"Our 22-year-old furnace finally gave up during a cold snap. Air Source had a new Lennox installed the next day. The difference is incredible—quieter, more even heat, and our gas bills are noticeably lower. Highly recommend!"— The Patterson Family, Orillia
Gas Furnaces Questions Answered
Common questions we receive about gas furnacesfrom homeowners throughout Central Ontario.
How long does a gas furnace last?
A well-maintained gas furnace typically lasts 20-25 years. However, efficiency declines with age, and repairs become more frequent after 15 years. We generally recommend considering replacement if your furnace is over 15 years old and requiring significant repairs.
What efficiency rating should I choose?
We recommend 96% AFUE or higher for most Ontario homes. While higher-efficiency furnaces cost more upfront, the energy savings quickly offset the difference—often within 3-5 years. For homes with high heating demands, 98% AFUE models make excellent sense.
How long does furnace installation take?
Most standard furnace installations are completed in one day, typically 4-8 hours. Complex installations requiring ductwork modifications or additional venting may take longer. We'll provide a clear timeline during your consultation.
Should I repair or replace my old furnace?
Generally, if your furnace is over 15 years old and the repair costs more than 50% of a new unit, replacement makes financial sense. We always provide honest advice—if a repair makes sense, we'll tell you.
What brands of furnaces do you install?
As a Lennox Premier Dealer, we specialize in Lennox furnaces—consistently rated among the best for quality and efficiency. We also install other major brands including Carrier and Keeprite to match various budgets.
Single stage, two stage, modulating—what's the difference?
Single-stage furnaces run at full capacity whenever they're on—simple and reliable. Two-stage furnaces have a low and high setting, running on low most of the time for quieter, more even heat and better efficiency. Modulating furnaces continuously adjust their output in small increments, providing the most precise temperature control, the quietest operation, and the highest efficiency. We'll help you choose the right option based on your comfort preferences and budget.
